Work-Package: M02-GMP-SANDBOX-CAPABILITIES-001

Agent: sindo-main-codex

Tests: capability/input/movement/terrain/camera/presentation; coordinate/streaming/docs/coordination; renderer dry-run 7/7

Fidelity: proves debug sprint/free-flight exclusion in Blizzlike335; no positive movement parity claim

+# M02-GMP-SANDBOX-CAPABILITIES-001 — Debug movement capability gate
+
+<!-- OPENWC_CLAIM:M02-GMP-SANDBOX-CAPABILITIES-001:sindo-main-codex:2026-07-16 -->
+
+## Ownership
+
+- Target: M02
+- Program: GMP/FND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m02-sandbox-capabilities`
+- Lease expires UTC: 2026-07-16
+- Integrator: M02 milestone integrator
+
+## Outcome
+
+Introduce an immutable local-player movement capability contract and require it
+at the movement boundary so debug sprint and free flight execute only in the
+explicit `RenderSandbox` profile and are rejected by `Blizzlike335`.
+
+## Non-goals
+
+- Claim that current movement values or `Blizzlike335` locomotion are 1:1.
+- Build a global application/profile framework before the application shell exists.
+- Remove debug Input Map actions or change their current sandbox bindings.
+- Implement jump, fall, swim, collision, server authority or reconciliation.
+- Mark M02 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/gameplay/movement/player_movement_capabilities.gd`,
+  `src/tools/verify_player_movement_capabilities.gd`, this claim
+- Shared/hotspots: `src/gameplay/movement/local_player_movement_controller.gd`,
+  `src/scenes/player/third_person_wow_controller.gd`, movement/input verifiers,
+  player regression scene, `docs/modules/local-player-movement.md`,
+  `docs/modules/player-input.md`
+- Generated/ignored: local `.godot`, native DLL, generated resources and renderer corpus
+
+## Contracts and data
+
+- `PlayerMovementCapabilities` owns immutable profile ID plus explicit debug
+  sprint/flight booleans and safe named factories.
+- `LocalPlayerMovementController` requires the capability value; missing input
+  falls back to `Blizzlike335`, never sandbox.
+- Player scene maps its exported profile selection once at the composition boundary.
+- Input actions and `MoveIntent` remain unchanged; rejected debug requests have no effect.
+
+## Dependencies
+
+- Requires: merged character presentation package on master `8c71e46`.
+- Blocks: final M02 integration audit and milestone closeout.
+- External state: none; verification is asset-free.
+
+## Verification
+
+- Pure profile factory/default and immutability regression.
+- Sprint accepted in RenderSandbox and ignored in Blizzlike335.
+- Flight toggle/vertical basis accepted in RenderSandbox and rejected in Blizzlike335.
+- Real regression scene verifies both profile compositions.
+- Existing input/movement/terrain/camera/presentation and renderer gates remain required.
+- Fidelity evidence: negative proof that debug capabilities cannot affect the
+  compatibility profile; no positive movement parity claim.
+
+## Documentation deliverables
+
+- Inline public API and profile semantics on the capability/controller boundary.
+- Updated movement and input specs: API, inputs/outputs, data flow, lifecycle,
+  failure/recovery, capability matrix and source map.
+
+## Simplicity and naming
+
+- Important name: `PlayerMovementCapabilities`.
+- Simplest approach: one immutable value injected into the existing controller.
+- Rejected complexity: autoload singleton, generic feature-flag service and global profile registry.
+- Unavoidable complexity: one profile-to-capability mapping at scene composition.
+- Measured optimization evidence: not applicable.
+
+## Status
+
+- State: active
+- Done: claim and isolated worktree from merged presentation master
+- Next: implement capability contract, gate controller/player and add regressions
+- Blocked by:
